Fig. 11 is a sectional view through the line Y Y. Fig. 12 is a sectional view through the line Z Z.

In the accompanying drawings similar let- 3 5 ters of reference refer to similar parts.

A represents the casing, which may be ofany desired size, but cylindrical in form and open at top and bottom. Intermediate the top and bottom of this casing there is provided 0 a plate B of a diameter equal to the'diameter of the casing and securely engaging the sides of the casing and which, in combina tion withthe upper portion of the casing, forms the tank for holding the gas. Below 5 the plate B there is inserted in the casing the carbid-box receptacle 0, which consists of an oblong box open at its forward end and having attached thereto a frame upon which is formed the projecting flange c, by means 6 of which it is riveted to the casing. The

Fig. 8 is a detailed perspective view door-frame c has formed upon its face the rib c and upon either side of the door-frame there are provided L-shaped projecting lugs 0 To this frame there is hinged upon one side the door 0 having upon its edge a rubher gasket 0. The door is adapted to be held in engagement with the frame by means of the crab 0 which passes around the doorand engages with the lugs c on both sides of the door-frame. On the inside of the carbid-box 6o receptacle 0 and upon both sides thereof I provide flanges a which act not only as a support for theoarbid-boxes when more than one is used, but serve the double purpose of directing the water which forms by reason of the condensation produced. by the contact of the hot gas upon the cold sides of the box into the receptacle attached to the lower carbid-box, hereinafter described.

I have shown two carbid-hoxes D and E,. which mayhave any desired number of partitions. At one end of the carbid-box D, I provide a tube (1, which communicates with the lower carbid-box E. Around the lower carbid-box E and forming the bottom thereof I have provided a drip-tank e, which receives v the moisture which may be condensed on the sides of the carbid-box receptacle.

On both sides of the casing I provide open lattice doors F and F, hinged or otherwise detachably secured to the side of the casing, which permits of the lower portion of the cas-. ing being entered for the purpose of repairing or cleaning any of the parts of the gen'erator contained therein. Upon one side of the casing I have provided two communicating sealed tanks or drums Gand H. These tanks are joined together by means of a communicating tube or pipe g, which maintains a uni- .form water-level therein, and for the purpose go of sealing said tanks and the pipes which onter the same I have provided on the side of 'thetank G afunnelg, which has a pipe coning the gas. In the bottom of the tank H there is provided. aciean-out 7L2, made of any desired form, by means of which the sediment, all. of which accumulates in this tank, may readily be removed I is the gasomete'r, cylindrical in form and of a diameter less than the diameter of the casing and having a closed top and open bottom and carried upon a supporting-rod t', securely mounted in the center of the plate B and having a telescoping connection with the rod 2' by meansof the casing t, At one side of the top of the gasometer I provide the cupchamber J, communicating with the gasometer and receiving the tubes as the gasometer descends. The cup-chambei-J hasa tubular extension j, which extends down into the gasometer and prevents siphonage above the line of the body of the water seal.

For the purpose of purifying and cooling the gas as the same arises from the generator I provide the deflecting communicating tubes K, as shown in Fig. 10. Arising from the generator there is a communicating pipe in, communicating with the drum or tank H.

Attached to the upperpart of the drum or tank Hand communicating therewith l have provided the U-shaped tubes In 76?, and at one side of the top of the drum or tank Hand extending into the same there is provided the pipe 7a, which carries the gas into the gasometer. The free end of the U-shaped cooling-tube 70 extends down into the drum H and is scaled. One member of the tube 7: and the lower endjof the tube 70 are surrounded by the partition 7a, which serves to direct the gas from is into Id. The upper end of the tube k is bent outwardly until it comes in line with the cup-chamber.J, thus doing away with two cupchambers.

The gas is conducted from the gasometer by means of the pipe g'', which has a T connection with the exit-pipe g". The lower end of the pipe extends down into the tank G and is sealed by the water therein.

As a safety-exit to the exterior I provide the pipe g which has an open-ended T connection with a pipe g communicating with the exterior at a point above the casing and has a telescopic engagement with the tubular extensionj oi the cup-chamber J. The tubular extension j has an aperture j near the line of the water seal of the gasometer, so that if for any reason the exit-pipe should become chrggctkor the gas be generated faster than it could be taken care of by the gasometer the gas would pass out through the opening'j thence up into and down through the tube g and thence to the exterior.

As an additional safeguard and in event of back pressure on the tube lt' when the carbidrcccptacle door is opened, the tube 1 between the tanks G and ll serves as a means of communicating with the exterior of the gasometer. The gas being forced back down the tube 7.3

will break the seal byforcing the water to v the gasometer andhaving sliding engagement with guideways upon the side of the casing. For the purpose of more readily engaging the lever Z with the aperture in I provide the projecting tongue in, which as the rod descends directs the lever into the slot.

For the purpose of cutting off the watersupply when it is desired to recharge the carbid-boxes I have provided lever N, securely fastened to the door and having a linked connection with the valve Z, which is closed when the door is opened.

.For the purpose of supplying water to the casing with which'to seal the gasometer I provide 'a funnel'Q on the side of the upper portion of the casing, which communicates with the interior thereof by means of the opening g.

In operation the carbid-boxee D and Ehaving been filled with. the c'arbid'they are inserted in the carbid-box receptacle and the door sealed in the manner heretofore described; The water-tank L having previously been filled and a suitable amount of water introduced into the gasomel'er by means of the foilnel Q, and the tanks G and 'H having been filled to the desired depth with water, the Water passes from the'water-tau k L down through the connecting-pipe Z into the upper carbidbox, when the gas begins to form and passes up into the cooling-tubes K and thence up into the gasometer, which causes the gasometer to rise, carrying with it the rod M, which as it ascends causes the lever l to lift and graduallyshut off the water-supply. Incaso,,for any reason, the lever should refuse'to act and the water-supply not being cut off gas should continue to be generated in a volume greater than the capacity of the gasomefer the gas gas has been generated and consumed, and it is again desired to recharge the carbid-l'ioxes, v

the door is swung open upon its hinges, cutting off the water-supply, the upper carbidbox being removed, and then the lower carbidbox removed, and the water which may have accumulated by reason of the condensation heretofore described is emptied from the drip tank formed around its outer edge, the carbidboxes being recharged and replaced. I I

it will be observed that by this form of multiple carbid-box the water comes in com tact with only a small portion of the carbid at a tiiue'and only successive cells and one-- cessive boxes produce or form gas.

Having thus fully described my invention, 7

what I desire to claini and secure by Letters Paten \id 1..
